When the converter detects the rising edge of the SON signal without faults, the RDY signal
turns to high level. When a fault occurs, t
he RDY signal turns to low level. The RDY signal
will keep at low level even if the fault is acknowledged, unless the converter detects another
rising edge of the SON signal again.
